Question: Five thousand randomly-selected MBA graduates were surveyed to determine their future plans. The survey response rate was 10%. The graduates' future plans were grouped into four categories for each of three majors, as shown in the following table:
-------------- MAJOR (Number of Graduates) ---------------
FUTURE PLANS Marketing (204) Finance (172) Operations (124)
Continue their education 26% 21% 24%
New position - existing company 39% 38% 41%
New position - different company 23% 28% 26%
Not sure 12% 13% 9%
The Business School Dean wants to determine if the future plans are significantly different for the three majors at a level of confidence of at least 90%. What test(s) would you recommend?
